If the NVM 24 stores one template, the processor 21 selects the template.

If the NVM 24 stores a plurality of templates, the processor 21 generates a preview image in which a code is added to the document according to the template. The processor 21 generates a preview image according to each template in response to an operation by an operator.

If the preview image is generated, the processor 21 controls the input device 26 to receive the selection of one of the templates from the operator. The processor 21 selects the template according to the operation of the operator.

The processor 21 may automatically select the template according to the document.

The processor 21 has a function of encoding the obtained identification information to a code.

The processor 21 encodes the identification information according to the selected template. Specifically, the processor generates the code by encoding the identification information according to an encoding format indicated by the template.

If the template does not indicate the encoding format, the processor 21 may generate the code by encoding the identification information according to a predetermined encoding format.

For example, the code is a one-dimensional code such as a JAN (Japanese Article Number) code. The code may be a UPC (Universal Product Code) or an EAN (European Article Number) code. The code may be a two-dimensional code such as a QR code. The code generated by the processor 21 is not limited.

The processor 21 has a function of generating a printed image obtained by adding the generated code to the acquired document.

The processor 21 generates the printed image obtained by adding the code to the document according to the selected template. The processor 21 transmits data of the document and the code to the RIP of the printer 28. The processor 21 transmits information about the size and position of the code to the RIP of the printer 28 according to the selected template. The RIP generates the printed image according to the information from the processor 21.

The processor 21 may generate the printed image without using RIP.

The processor 21 has a function of printing the generated printed image on the paper using the printer 28.

The processor 21 transmits a signal for printing the printed image to the printer 28. The printer 28 prints the printed image generated by the RIP according to the signal. The processor 21 may print the printed image after the input device 26 receives an operation of performing the printing.

The processor 21 has a function of reading the code 103 from the scanned image.

The processor 21 specifies the area of the code 103 from the acquired scanned image. For example, the processor 21 specifies the area of the code 103 using a predetermined object recognition. If the area of the code 103 is specified, the processor 21 decodes the code 103. The processor 21 acquires the identification information obtained by decoding the code 103.

The processor 21 has a function of controlling the communication I/F 25 to transmit the identification information obtained by decoding the code 103 and the image of the entry field 102 in the scanned image to the server 10 in an associated manner.

The processor 21 controls the communication I/F 25 to transmit the identification information obtained by decoding the code 103 and the scanned image to the server 10 in an associated manner. For example, the processor 21 controls the communication I/F 25 to transmit the identification information and the scanned image as one request to the server 10.

The processor 21 may extract the area in which the entry field 102 is recorded from the scanned image. For example, the processor 21 extracts the area in which the entry field 102 is recorded from the scanned image using the predetermined object recognition. The processor 21 may control the communication I/F 25 to transmit the identification information and the image of the extracted area to the server 10 in an associated manner.

Next, functions of the server 10 are described. The functions of the server 10 are performed by the processor 11 executing the programs stored in the ROM 12 or the NVM 14.

First, the processor 11 has a function of acquiring data of the document relating to the service of the task indicated by the identification information acquired by the image forming apparatus 20 to the image forming apparatus 20 through the communication I/F 15.

The processor 11 controls the communication I/F 15 to receive a request for storing the identification information acquired by the image forming apparatus 20 from the image forming apparatus 20. If the request is received, the processor 11 acquires the data of the document relating to the service specified by the identification information stored in the request from the NVM 14. If the data of the document is acquired, the processor 11 controls the communication I/F 15 to transmit a response for storing the document data to the image forming apparatus 20.

If the NVM 14 stores a plurality of types of documents relating to the service, the processor 11 controls the communication I/F 15 to transmit a response including the list of a plurality of types of documents to the image forming apparatus 20. Thereafter, the processor 11 controls the communication I/F 15 to receive a request for transmitting one document type selected from the list from the image forming apparatus 20.

The processor 11 has a function of storing the identification information and the image of the entry field 102 in an associated manner.

The processor 11 controls the communication I/F 15 to receive the identification information and the image of the entry field 102 associated with each other from the image forming apparatus 20. The processor 11 stores the received identification information and image of the entry field 102 in an associated manner in the NVM 14.

Next, an operation example of the management system 1 is described.

First, an operation example in which the management system 1 performs printing on the service paper 200 is described. FIG. 5 is a sequence diagram illustrating an operation example in which the management system 1 performs printing on the service paper 200.

First, the processor 21 of the image forming apparatus 20 acquires the identification information (ACT 11). If the identification information is acquired, the processor 21 controls the communication I/F to transmit the request for storing the identification information to the server 10 (ACT 12).

The processor 11 of the server 10 controls the communication I/F 15 to receive the request. Here, the NVM 14 stores a plurality of types of documents relating to the service specified by the identification information stored in the request.

The processor 11 controls the communication I/F 15 to transmit the response including a list of the document types to the image forming apparatus 20 (ACT 13).

The processor 21 of the image forming apparatus 20 controls the communication I/F 25 to receive the response. If the response is received, the processor 21 selects one of the document types from the list according to the user input through the input device 26 (ACT 14).

If the document type is selected, the processor 21 controls the communication I/F 25 to transmit the request requesting the data of the selected type of the document to the server 10 (ACT 15).

The processor 11 of the server 10 controls the communication I/F 15 to receive the request. If the request is received, the processor 11 of the server 10 controls the communication I/F 15 to transmit the response including the data of the document to the image forming apparatus 20 in response to the request (ACT 16).

The processor 21 of the image forming apparatus 20 controls the communication I/F 25 to receive the response. If the response is received, the processor 21 generates a preview image based on the document data stored in the response (ACT 17). Here, the NVM 24 stores a plurality of templates.

If the preview image is generated, the processor 21 controls the display 27 to display the preview image (ACT 18).

If the preview image is displayed, the processor 21 selects a template according to the user input through the input device (ACT 19). If the template is selected, the processor 21 encodes the identification information (ACT 20).

If the identification information is encoded, the processor 21 generates a printed image including the encoded code using the RIP according to the selected template (ACT 21). If the printed image is generated, the processor 21 controls the display 27 to display the printed image as the preview image (ACT 22).

If the printed image is displayed on the display 27 as the preview image, the processor 21 transmits a signal for printing the printed image to the printer 28 (ACT 23).

The printer 28 receives the signal. If the signal is received, the printer 28 prints the printed image on the paper (ACT 24). If the printer 28 prints the printed image on the paper, the management system 1 terminates the operation.
